2 / 50 page ES I ES I 2 Rev. 0A January 5, 2006 ES29LV800E Excel Semiconductor inc. The ES29LV800 is a 8 megabit, 3.0 volt-only flash memory device, organized as 1M x 8 bits (Byte mode) or 512K x 16 bits (Word mode) which is con- figurable by BYTE#. Four boot sectors and fifteen main sectors are provided : 16Kbytes x 1, 8Kbytes x 2, 32Kbytes x 1 and 64Kbytes x 15. The device is manufactured with ESI’s proprietary, high perfor- mance and highly reliable 0.18um CMOS flash technology. The device can be programmed or erased in-system with standard 3.0 Volt Vcc supply ( 2.7V-3.6V) and can also be programmed in stan- dard EPROM programmers. The device offers min- imum endurance of 100,000 program/erase cycles and more than 10 years of data retention. The ES29LV800 offers access time as fast as 70ns or 90ns, allowing operation of high-speed micropro- cessors without wait states. Three separate control pins are provided to eliminate bus contention : chip enable (CE#), write enable (WE#) and output enable (OE#). All program and erase operation are automatically and internally performed and controlled by embed- ded program/erase algorithms built in the device. The device automatically generates and times the necessary high-voltage pulses to be applied to the cells, performs the verification, and counts the num- ber of sequences. Some status bits (DQ7, DQ6 and DQ5) read by data# polling or toggling between consecutive read cycles provide to the users the internal status of program/erase operation: whether it is successfully done or still being progressed. The ES29LV800 is completely compatible with the JEDEC standard command set of single power sup- ply Flash. Commands are written to the internal command register using standard write timings of microprocessor and data can be read out from the cell array in the device with the same way as used in other EPROM or flash devices.
